Popis:	Between February 1996 and January 2000, parasitological examination of Scomber scombrus ( n = 447), Trachurus trachurus ( n = 175), Sardina pilchardus ( n = 160) and Engraulis encrasicolus ( n = 153) from the fishing-ground of Tarragona (NE Spain) were made for anisakids. Three anisakid species ( Anisakis larva type I sensu Berland, 1961 , Contracaecum sp. and Hysterothylacium aduncum ) were morphologically identified. The prevalence of Anisakis larva type I sensu Berland (1961) ranged from 11.0% ( S. scombrus ) and 2.6% ( T. trachurus ) to 0.0% ( S. pilchardus and E. encrasicolus ). The prevalence of H. aduncum in S. scombrus was 1.1%. The prevalence of Contracaecum sp. was 2.0% in S. scombrus , and 0.7% in T. trachurus respectively. There was a positive and significant correlation between the host length and the number of Anisakis larva type I sensu Berland, 1961 found in S. scombrus .
